Beitknown that l'fJo'sEPH KLEIDMANN, a

' subj'ectof the '(lzar'cf Russia, and resident of the city of NewYorkjin the 'countyof New '1 York and State ofNew' York, have inventedcertain new and useful lmproven'ients in {Papa- Fe'edingll/lachiries; ofwhich the following" is a specification.

The present 'invention relates to paper feeding machines which areadapted for use on printing presses, ruling machines, and on similarapparatus by means of which single sheets are fed regularorder ofsuccession from a pile or stack of paper, suitably arrang'ed'ona'table'located near to the apparatus. Among other devices there havebeen used heretofore for this purpose feeding cylinders, secured to' a'bracket, suitably ar' ranged on a shaft, to which bracket had beenfastened one or more fingers, which latter serve the purpose of allowingthe feeding cylinders to engage the sheets at a suitable "distance fromthe front edge thereof and then'feed the sameto devices which deliverthem to the'printing press or to a similar machine. One serious defectof this device consists ilithe fact that the fingers, mentionedhereinbefore, tear the paper on'it's front edge, for the reason that thewhole weight of the feeding cylinders rests on these fingers and thus onthe paper, and the fingers are thereby liable to tear the latter whenreachin the front edge of'the paper sheet,

"in which position the cylinders and fingers rest on one'sheetonly.Another serious defect is due to the arrangement of the cylin- 'ders'relative to the fingers, or more: particula rly due to the fact that thecylinder'sare normally out of engagement with the paper and engage thesame only when the fingers are disengaged with the same, and sincecertain machines require a great speed, it is obvious that thefeedingcylinders will at such a great speed not be able to engage thepaper "same at all.

" :fore mentioned, and its lirst object is to construct a""-s1m'ple andinexpensive device,

whichfis a'd'aptedtoseparate in regular suc- "c'ession'singlesheets froma stack of paper, suitably arranged near to the printing press.

Another object ofthe invention is to provide feeding rollers, which restnormally on the paper, but becomeoperative only at a certainandpredetermined distance from the edge of the paper, preventing thus thefingers, to which'said rollers are attached, from tearing the sheets ofpaper. I

A further object of the invention is to provide meanswhich hold theother sheets of paper from movement, while the top sheetis beingadvanced and removed.

' A still further object of the invention is to accomplish all theaforesaid operations in a positive, efiicient and simple manner, and ina continuous cycle of operation.

These and other objects'and advantages will more fully appear in readingthe specification and from the inspection of the drawings forming partof this application.

' Broadlyspeaking, 'upon the main shaft of the apparatus are mounted aplurality of cams or eccentrics, which operate the feeding rollers, towhich are attachedfingers which rest together with the rollers on thesheet of paper and allow the rollers to rotate as long as the fingersare engaged with the aper. As soon as the fingers are disengage with thepaper, the rotation of the rollers is stopped, whereby the aper is fedto a mechanism, transporting t e sheets to the printing press or similardevice.

The invention consists further of the combination and arrangement ofparts, the construction'of th'edevice and the location of themechanisnn'which will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of theimproved apparatus and Fig. 2 a front view'of amodification of theapparatus. Figs. 3 and 4 are details of construction, showing the devicewhich holds the other sheets of paper from movement, while the top sheetis being advanced and removed. Fi 5 is a detail of construction, showingthe location'oi the advancing means at or about the beginning of itsforward movement, Fig. 6 is a similar view of the same mechanism,showing its position at that point where thefeeding rollers becomeoperative, Fig. 7 is a similar viewofthe device, showing theoutermostposition ofthe advancing means and Fig. 8 shows the advancingmeans in their raised position and about to start backward. Fig. 9 is aperspective view of the advancing means. Figs. 10, 11 and 11 illustratedetails of construction. Figs. 12, 13, 14, 15 and 16 are detail views ofmodifications of the advancing means.

in the drawings, 1 designates one of a pair of the side frames of thefeeding machine, connected by means of screws 2, 2, to the side frames 3of the printing press. The side frames 1 may be connected by anysuitable members, as, for instance, in the present case by means oftie-rods 4.

The stack of paper is indicated in the drawings at 5 and is supported ona table 6, which is automatically raised by means, hereinafter to bedescribed. The stack of paper is guided in its upward movement by atransverse vertical wall 7 having a forwardly bent lip 8, unto which thepaper is brought by the feeding mechanism, which forms an essential partof the present invention.

The main shaft 9 of the apparatus is journaled in suitable bearings inthe frame and is rotated from the cylinder shaft 10 of the printingpress by any suitable means, such as, for instance, sprocket-wheels 11and 12,-

mounted on the shafts 10 and 9, respectively, and a chain 13,transmitting the rotation of the cylinder shaft 10 to the main shaft 9of the apparatus. This main shaft 9 operates through the medium ofsuitable intermediate means the feeding rollers of the apparatus.

in order that the operation of and the connection between the feedingroller carrying means and the main shaft of the ap aratus be moreclearly understood, first t e construction of the feeding rollers andthe principle upon which they work will be described.

The sheet feeding or advancing means comprise one or more rollersmounted on a forked lever, which lever is provided with a finger, whichallows the roller to rotate, or arrests the rotation of the same, sothat it may act upon the sheet of paper and convey the same to meanswhich transport the sheets to the printing press. The principle ofoperation of these feed rollers or advancing means is the following: Therollers come into contact with the paper and are moved forward, rotatinguntil a predetermined point from the front edge of the paper, wheretheir rotation is stopped. As far as this the paper is not advanced, dueto the rolling motion of the rollers. Since, however, these rollers areprovided with a friction covering, and the top sheet rests on paper oron a friction covering, somewhat smoother than the covering of therollers, it is obvious that the top sheet will be separated from thestack of paper and moved forward as soon as the rotation of the rollersis arrested. The rollers are then disengage the paper and move forwardbut do not advance the sheet until their rotation is stopped; advancethe sheet and are then raised, moved backward and then again broughtinto engagement with the paper.

The means for effecting this motion will be 7 hereinafter more fullydescribed.

In Figs. 5 to 9 of the drawings, the different stages of operation ofthe advancing means are shown. The feeding roller 14 is loosely mountedupon a shaft 15, which in turn is rotatably ournaled on a forked lever16, loosely carried by a lever 17, which is adj ustably mounted on anoscillating and alternating shaft 18. As mentioned hereinbefore, theroller 14 is loosely mounted on the shaft 15; the roller would thus notnecessarily participate in the rotation of the shaft. In order that theroller should rotate with the shaft, but still be flexibly connected tothe same, a spring 19 is arranged on the shaft,

engaging the roller 15 and an adjustable washer 20, by means of whichthe tension of said spring may be adjusted so that the connectionbetween the roller and shaft be more or less rigid. The roller 14 isprovided with a friction covering 21, preferably made of rubber, or ofany suitable material, the coefficient of friction of which is greaterthan that of paper upon paper. FiXedly secured to the shaft 15 isfurthermore a ratchet 22, adapted to be engaged by a projection 23 of alever 24, pivoted at 25 to the forked lever 16. The lever 24 carries onits free end a finger 26, adjustably secured thereto. Normally, that iswhen the finger 26 rests upon the surface of the top sheet, theprojection 23 does not engage the ratchet 22, and thus the roller 14 isallowed to rotate freely, but as soon as the finger 26 is disengagedwith the paper and allowed to fall down, the projection 23 engages theratchet, whereby its rotation is stopped and the friction between thepaper and the roller carries the top sheet forward within the reach ofthe trans oorting means, hereinafter to be describe shaft 18 isreciprocably mounted in horizontal guides 180 and has attached thereto alever 27, carrying a roller 28, slidably arranged in a substantiallyhorizontal guide 29, which in turn is slidably arranged in asubstantially vertical guide 30. It will thus be seen that inalternating the shaft 18 and raising and lowering the guide 29, thefeeding roller will be moved forward, raised, moved backward andlowered, as the guide is raised and lowered and the shaft is moved toand fro. in order to alternate the shaft 18, the same is engaged by anarm 31, piv- The r 16, relative to side framest o-f the.machine.v To.this. rockshaft is rigidly secured an arm 3.4, engaging the. properlyconstructed groove 35 of a cam 36, fixedly secured upon the. main shaft9. By means 'oftheseconnections, the rollers 14 ar'ealternated upon thesurface of the paper, whileby means of. the-cam36, carried; by theshaft. 9, and the lever 37', pivoted at 38 and engaging the. horizontalguide 29: and the cam 36, the. rollers are lowered, and raised. Thecam36 doesnot operate upon the lever 37' until; the. rock-shaft has.caused? the shaft l8 to. move toward. the front edge of; the sheet of;paper toits outermost position, in which position the. rollers 14. havebrought the sheet of paper within the reach of the transportingmechanism, hereinafter to be described. The cam 36 acts then upon. thelever-37, lifting thereby the horizontal. guide 29, whereby, the shaft1:8 isgivena turn and the rollers. 14. arev disengaged with the topsheet of the ile of paper. The cam. 36 keeps the gui, e 29 in, its,elevated position until the shaft 18 is brought by the groove 35. of;the cam 36 and the mechanism operating therewith into its innermostposition, at which place the spring 364, shown. in Fig. 2 of thedrawings, brings the guide 29 back to its lower position, giving therebythe shaft 18.; a. turnso that the rollers 14. engage. again the topsheet of, the. pile of, paper.

The angular osition of thev forked levers e shaft. 18 may be adjusted bymeansof a set screw 39, engaging a prO- jection 40, carried by the lever17. A spring 47; engages theprojections40 and the lever 16 in order tokeeptherollers incontact with the paper and to exert the desireddegreeof pressure on the surface of-the. paper. It is obvious that therollers. should. engage the paper: always undera certain predeterminedangle in order that their operationshould be the most'effectve. The setscrew. 39' predetermines this angle, and is usually set so that. theroller will engage the paper under nearly themost efiective angle, evenwhen the paperisnot raisedto its normal level.

To theoscillating shaft 18 is rigidly attached a,rod 48, carrying anadjustable arm 49, forkedat- 50. In this forked end of the arm- 49 ismounteda roller 51 and means in: dicated at 52 whichwill allow theroller to rotatewhen the. same moves with the feeding rollersforwardly,but prevents. the rota: tion of the same in the other direction. Thedistance between thefeeding rollers. and the roller-51 issuch, that theroller; 51 engages always. the sheet next tothe .top sheet of the stackof paper. When, therefore, the feeding rollers move forward, the roller51 will engage the sheet which lies under the top sheet, and will thusprevent; the removal of the same. Should, however, for-somereason,thesecondsheetmovewith thetop sheet, it will tend to move the roller 51backward,

which turn effects. a brakingor retarding action. on this sheet,andprevents thus. its re: moval. The roller 51 may be provided ob,-viously, with a. friction covering.

On, the lip 8 of the transverse wall 7,. here,- inbefore referred to,is. arranged a slightly inclined table 53, having friction strips 54,arranged under the rollers 14, which are preferably made of rubber, thefriction surface. of which is somewhat smoother than hat of the frictionroller 14, orin other words, the coefficient of: friction of the feedingrollers 14 has a greater value than that of the friction strips 54.Adjacent to these friction stripsand in thepath of the fingers 26 areformed recesses 55. in the: plate 53; into which thefingers26 lower whenmoved beyond the front edge of the top sheet. The object of thisconstruction is to arrest, the rotation of the rollers. 14atapredetermined point; from the front edge of the sheets, so as to.move the top. sheet forward. The top sheet of the stack of paper isadvanced by the rollers until it is Within the reach of the conveyingmeans, consisting of rollers 56, mounted on a shaft 57, rotated by meansof a chain 58 and sprocket-wheelv 59 from the main shaft of theapparatus, and feeding belts 60, running over rollers 61, journaled inbrackets 62, which are attached to the inclined table 68, on which thesheet slides unto the cylinder of the printing press, Pressure. rollers64 rest normally on the rollers 56, and are mounted on a lever 65,pivoted at 66, the free end of which levers carry rollers 67 in contactwith cams 68, arranged on the main camshaft 9 of the apparatus. A secondset of pressure rollers 69 are carried byrods 70, pivoted at 66 to thelevers 65, carrying the pressure rollers; 64. It is obvious that thepurpose of the cams 68 is to raise and lower the pressure rollers 64. attimes when the front edge of the top sheet of the stack of paper reachesthe rollers 56. The feed bands deliver the sheets to the cylinder oftheprinting press, it being, of course, obvious that means must beprovided, whereby the sheet is brought into the proper position relativeto the cylinder. This means isindicated at 71, and is operated by meansof the outer surface of the cam 36 through intermediary of 2. connecting rod 74, secured to an arm 7 5, having a roller 76 in contact withthecam 86. These adjusting means form the subject matter of anotherapplication and are here only indicated inorder to complete thedescription of the machine. In order to keep the other sheetsback. asthetop sheet is being fed off, a gripper is provided, which is carried by arod 77, journaled at 78 and 79 upon the frame of the machine and comprisng an arm 80, carried by the rod 77, towhich arm is attached aconnecting rodj81, to the latter being pivoted a finger 82, normallykept upon the stack of paper by means of a spring 83. The shaft 77 isoperatively connected to a cam 84, mounted upon the main shaft of themachine. The connection between the cam and the rod 77 is made by meansof an arm 85, rigidly secured to the rod 77 and engaged by the forkedend of a connecting rod 86, which latter carries a roller 87,operatively engaging the cam 84. It will be easily seen that when theroller 87 is engaged by the cam 84, the finger 82 is lifted, or in otherwords, disengaged with the paper and allows the top sheet to be removed,but as soon as the top sheet is moved for a distance, the finger 82engages the other sheets just back of the rear edge of the top sheet ofthe paper and prevents thus the movement of the same.

As mentioned hereinbefore, the stack of paper is supported on a table 6,which is automatically raised by means of a device, which forms thesubject matter of another application for Letters Patent. Moreparticularly, the table is supported by endless lines 88 and 89, whichlatter is secured to a pulley 90, mounted on a shaft 91, carrying a wormgear 92 in mesh with a worm 93, which is operated by means in contactwith the stack of paper.

Frequently mutilated or torn sheets are contained in the stack of paper,and it is obvious that when such sheets are fed to the printing press,serious troubles arise. More particularly the cylinder prints upon thepaper and at the mutilated places upon the support of the paper; whenthus the next sheet is printed, the reverse side of the same is usuallyinked in by the ink being upon the support of the paper at places wherethe )re ceding sheet was mutilated or torn. t is thus obvious that meansshould be provided which stop the operation of the printing press andthe feeding machine, when a mutilatedsheet is fed to the press. For thispurpose an oscillating arm 96 is mounted upon the frame of the machine,and connected by means of a, preferably, rigid connection, shown at 97,to the power transmitting apparatus, located between the main shaft ofthe printing press and the shaft of the motor or any other suitabledevice, operating the printing press. The arm 97 is normally kept inthis position, that is in a position, whereby the two shafts,hereinbefore mentioned, are connected, by means of a bellcrank 98,pivoted at 99, and being provided with a nose 100, engaging a projection101 of the lever 96. In order to keep the bellcrank 99 in engagementwith the lever 96, a lug 102 is provided, pivoted at 103. The free endof this lug forms the armature 104 of an electro-magnet 105. One end ofthe winding of the electro-magnet is connected to the frame of themachine, while its other end leads to a battery 105, the free terminalof which is connected preferably to the pressure rollers 64 and tieadjusting means 71. The bellcrank 98 holds the lever 96 in its operativeposition against the tension of a spring 106, connected to the lever 96and the frame of the machine. Normally, that is when a whole sheet ofpaper passes through the conveying and pressure rollers, itinsulates thepressure rollers from the frame of the machine. Should, however, thesheet be torn or mutilated, a contact is closed from the frame, throughthe magnet, through the battery to the pressure roller and thus to theconveying rollers. The electro-magnet is thus energized, and attractsthe armature 104, allowing the spring 98 to act, whereby the nose 100 isdisengaged from the projection 101 of the lever 96, and the spring 106is adapted to act, shifting thus the lever and disconnecting the powertransmitting apparatus, whereby the machine will immediately come torest.

The operation of the device is as follows: The sheets of the stack ofpaper are moved by the feeding rollers forward unto the slightlyinclined table 53, it being obvious that the top sheet owing to theslight inclination is moved further outward than the suhsequena, sheets.This position can be imparted to the sheets either by hand or by themachine proper, when worked. If now the machine is started and thus thecamshaft 9 rotated,

the feeding rollers will be first in the position shown in Fig. 5 of thedrawings, that is the fingers 26 and the rollers 14 rest on the topsheet, and thus the projections 23 of the finger carrying arms 24 do notengage the ratchets. The rollers 14 will, therefore, rotate freely, anddo thus not move the paper. At the same time roller 51 engages the sheetnext to the top sheet and moves thereon in the manner, hereinteforedescribed. When now the fingers 26 reach the front edge of the top sheetwith their rear edge, the fingers will fall down into the recesses 55and thus the projections 23 will engage the ratchets, (Fig. 6 of thedrawings), whereby the rotation of the rollers is stopped, and thelatter being provided with a friction covering of more or less adhesivematerial, will carry forward the top sheet. The sheets lying underneaththe top sheet are prevented from movement by the friction covering 54,arranged in the path of the rollers, which covering produces a frictiongreater than that between two subsequent sheets. On the other hand, assoon as the top sheet starts its movement, the finger 82 engages thesheet lying under the top sheet and keeps the same in position. W henthe feeding rollers have reached their outermost position, as shown inFig. 7, the top sheet is within the reach of the conveying rollers 56,at which time the pressure rollers 64 are moved downwards, whereby thesheet is conveyed unto the printing press (Fig. 8 of the drawings). Assoon as the feeding rollers 56 engage the sheet of paper, the fingersand feeding rollers 14 are moved upwards and backwards, into contactwith the next sheet.

Attention is called to the fact, that the construction of the cam grooveis such, that the rollers 14 and the fingers contact with and aredisengaged from the paper with a speed which is practically equal tozero.

Vv hen for some reason the friction strips are not covered by a sheet ofpaper, and no forked end of the rod 109,

sheet is advanced, it is obvious that the friction covering of therollers 14 will slide on the friction strips 54, whereby the arms,supporting the rollers 14, would be liable to break or to stop theoperation of the machine. This is prevented by the flexible connectionbetween the rollers and the shaft of the same, as hereinbeforedescribed.

A modification of the feeding rollers and finger is shown in Figs. 12 to15 of the drawings. In this case a roller 107 is mounted on the forkedend 108 of the bar 109, which latter is mounged in the manner,hereinbefore described, upon an arm 17, engaging the shaft 18. The.roller 107 is again provided with a friction covering 21. A finger 110is adjustably mounted upon a U-shaped memher 111, loosely mounted on theshaft 112 of the roller 107, and carrying loosely behind the roller ashaft 113, to which is fixedly se cured a pawl 114. Normally, that iswhen the finger and roller rest on the pa )er, the

awl 114 rests against the back wa of the As the finger 110 is loweredinto the recess 55, the pawl 114 is forced by the weight of the fingerand U- shaped bar 111 against the roller 107 and stops thus the rotationof the same. An other modification of these feeding rollers and fingersis shown in Fig. 16 of the drawings, in which a pawl 115 is arranged infront of the rollers, the operation of the same being, of course, thesame as the one, hereinbefore described. I

From the inspection of the drawings, it will be understood that themachine may operate upon sheets of different thicknesses and size,without changing in any way whatever the position of the parts of themachine. It is, on the other hand, obvious that many minor changes maybe made in the construc tion of the parts and assembling the samewithout departing from the spirit and scope of the invention. Forinstance, one modification is shown in Fig. 11 of the drawings, in whichthe lever 27 on the shaft 18 is provided with two rollers 116 and 117,engaging a guide 118, which is mounted on a reciprocating arm 119,sliding in the guides 120 and operated by the cam 36, hereinbeforedescribed.

Another modification is shown in Fig. 2 of the drawings, in which theshaft 18 is provided with rollers 181 and 182, engaging the horizontal.guides 183, attached to the side frames 1,1 of the machine.
